Description

Technical Field

[0001] This invention belongs to the field of textile equipment technology, and in particular relates to a textile toughness testing device. Background Technology

[0002] Textiles refer to materials made from natural or chemical fibers through spinning, weaving, dyeing, and finishing processes. They mainly include three categories: woven fabrics, knitted fabrics, and nonwoven fabrics. Modern textiles have transcended traditional clothing functions, developing towards functional and intelligent directions. Common varieties include woven fabrics, knitted fabrics, nonwoven fabrics, and composite fabrics. Toughness testing is an important indicator for measuring the durability of textiles. Toughness testing of textiles mainly includes tests for multiple mechanical indicators such as breaking strength, tear strength, bursting strength, and abrasion resistance.

[0003] A Chinese patent application (or patent) with publication number CN215574356U discloses a fabric toughness testing device, including a base, a fixing frame and a tension module mounted on the base. The fixing frame includes a bracket, a connecting strip and multiple tension sensors. One end of the connecting strip is connected to one end of each tension sensor, and the other end is connected to one end of the fabric to be tested. The other end of the tension sensor is connected to the bracket. The tension module includes a mounting frame, a roller mounted on the mounting frame, and a power source for driving the roller.

[0004] However, the above-mentioned device still has the following problems during implementation: During the fabric testing process, the fabric is stretched using a winding device, and then multiple tension sensors are used to detect the tension of the fabric. However, the tension that the fabric experiences in actual use is often not horizontal tension, but torsional tension, and the device can only stretch the fabric horizontally, which limits its testing capabilities.

[0005] A Chinese patent application (or patent) with publication number CN222379498U discloses a fabric toughness testing device, including a base; a lifting mechanism for lifting operations, which is mounted on the base; a clamping mechanism for clamping the fabric, which is mounted on the lifting mechanism; and a side-pushing mechanism for applying pressure to the side of the fabric, which is mounted on the base.

[0006] However, the above-mentioned device still has the following problems during implementation: During fabric inspection, the two ends of the fabric are first fixed by clamps, and then the fabric is horizontally stretched by an electric push rod. After the inspection is completed, an additional motor is needed to drive the clamps to rotate and to twist the fabric, resulting in a complex structure and high cost.

[0007] To address this issue, we provide a textile toughness testing device. Summary of the Invention

[0008] The purpose of this invention is to provide a textile toughness testing device. By combining a positioning mechanism, a horizontal tensioning mechanism, and a torsion mechanism, this invention solves the problem that existing textile toughness testing devices only have horizontal tension testing capabilities, which limits their testing capabilities.

[0009] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0010] This invention relates to a textile toughness testing device, comprising a testing platform. A positioning mechanism is located on the top of the testing platform.

The positioning mechanism positions the fabric. A horizontal stretching mechanism is also located on the top of the testing platform. The horizontal stretching mechanism includes a fixed plate movably connected to the surface of the rotating column, with an opening on the top of the fixed plate. The device includes a convex groove in the fabric, a movable shaft slidably connected inside the convex groove, a tension gauge mounted on one side of the fixed plate, and a drive assembly located inside the testing platform. A horizontal tensioning mechanism is used to test the horizontal tension of the fabric. A torsion mechanism is located on one side of the movable shell. This torsion mechanism includes a rotating shaft movably connected inside the movable shell, a first gear mounted on the surface of the rotating shaft, an arc-shaped toothed plate meshing with the bottom of the first gear, a support frame located at the top of the testing platform, a baffle mounted on one side of the support frame, and a limiting assembly located inside the movable shell. The torsion mechanism performs a torsion test on the fabric.

[0011] The present invention is further configured such that the clamping assembly includes a first clamping plate installed on one side of the tension gauge, a second clamping plate installed on one side of the rotating shaft, a rotating pressure plate movably connected inside the first and second clamping plates, a fixed shell installed on one side of the rotating pressure plate, a fixed seat installed on one side of the first and second clamping plates, a rotating seat movably connected inside the fixed seat, a screw installed on one side of the rotating seat, and a knob threadedly connected to the surface of the screw.

[0012] The present invention is further configured such that a limiting groove is formed inside the fixed shell, and one side of the screw passes into the limiting groove.

[0013] The invention is further configured such that the top of the movable shaft is fixedly connected to the support rod, and the arc-shaped toothed plate and the baffle are kept at the same horizontal position.

[0014] The invention is further configured such that the detection platform includes a support base installed at the bottom of the fixed plate, and the bottom of the support frame is fixedly connected to the support base.

[0015] The present invention is further configured such that the driving assembly includes a driving motor installed inside the support base, a second gear installed at the output end of the driving motor, and a third gear installed on the surface of the rotating column, wherein one side of the second gear meshes with the third gear.

[0016] The present invention is further configured such that the limiting component includes a guide groove formed on the top of the fixed plate, a cam mounted on the surface of the rotating shaft, a limiting shell slidably connected to the surface of the cam, a moving rod mounted on the bottom of the limiting shell, a pulley movably connected to the bottom of the moving rod, and a tension spring sleeved on the surface of the moving rod.

[0017] The invention is further configured such that a support plate is slidably connected to the surface of the movable rod, and one side of the support plate is fixedly connected to the inner wall of the movable shell.

[0018] The invention is further configured such that a slide block is fixedly connected to the bottom of the arc-shaped toothed plate, and an arc-shaped rod is slidably connected inside the slide block.

[0019] The invention is further configured such that a connecting seat is fixedly connected to the surface of the arc-shaped rod, one side of the connecting seat is fixedly connected to the movable shell, and springs are sleeved on both sides of the surface of the arc-shaped rod.

[0020] The present invention has the following beneficial effects: The present invention drives the rotating column to rotate by a drive motor, and with the sliding guide of the convex groove and the moving shaft, the horizontal displacement of the moving shell is realized, thus completing the horizontal tensile test of the fabric; at the same time, the contact between the arc-shaped toothed plate and the baffle pushes the first gear to drive the rotating shaft and the second clamping plate to rotate, thus realizing the fabric torsion test. The entire process does not require an additional power source, and both tensile and torsion tests can be completed by relying on the same drive component, which simplifies the equipment structure, reduces manufacturing costs, and can sequentially perform horizontal tensile and torsional tensile tests on the same fabric, resulting in more comprehensive test data. This makes up for the shortcomings of existing equipment in testing only one type of material, and effectively improves the accuracy and reliability of textile toughness testing.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Please refer to Example 1 Figures 1-11 This invention relates to a textile toughness testing device, comprising a testing platform 1, a positioning mechanism 2 on the top of the testing platform 1, the positioning mechanism 2 including a rotating column 21 on the top of the testing platform 1, a fixed plate 22 installed on one side of the rotating column 21, a telescopic tube 23 installed on one side of the fixed plate 22, a support rod 24 slidably connected inside the telescopic tube 23, a movable shell 25 installed on one side of the support rod 24, and a clamping assembly 26 on one side of the fixed plate 22, wherein the positioning mechanism 2 positions the fabric; a horizontal stretching mechanism 3 is provided on the top of the testing platform 1, the horizontal stretching mechanism 3 including a fixed plate 31 movably connected to the surface of the rotating column 21, and a convex shape formed on the top of the fixed plate 31. The system includes a groove 32, a movable shaft 33 slidably connected inside the convex groove 32, a tension gauge 34 installed on one side of the fixed plate 22, and a drive assembly 35 located inside the detection platform 1. The horizontal tension of the fabric is detected by the horizontal tensioning mechanism 3. A torsion mechanism 4 is provided on one side of the movable shell 25. The torsion mechanism 4 includes a rotating shaft 41 movably connected inside the movable shell 25, a first gear 42 installed on the surface of the rotating shaft 41, an arc-shaped toothed plate 43 meshing with the bottom of the first gear 42, a support frame 44 located on the top of the detection platform 1, a baffle 45 installed on one side of the support frame 44, and a limiting assembly 46 located inside the movable shell 25. The fabric is subjected to torsion testing by the torsion mechanism 4.

[0037] Specifically, in the aforementioned textile toughness testing device, the rotating column 21 supports and drives the fixed plate 22 and the movable shell 25 to rotate together. The telescopic tube 23 provides a telescopic guide channel for the support rod 24, allowing the support rod 24 to slide smoothly inside it. The support rod 24 connects to the movable shell 25 and transmits horizontal displacement, realizing the position adjustment of the movable shell 25. In the aforementioned textile toughness testing device, the movable shell 25 houses the torsion mechanism 4 and moves with the support rod 24. The fixed plate 31 provides a rotation support point for the rotating column 21, enabling the rotating column 21 to rotate... The convex groove 32 guides the moving shaft 33 to slide along a specific trajectory, controlling the horizontal stretching path. The moving shaft 33 connects to the support rod 24 and pushes it out, converting the rotational motion into linear displacement. In the above-mentioned textile toughness testing device, the tensile gauge 34 detects the tensile force value of the fabric in real time and feeds back the test data. The rotating shaft 41 drives the second clamping plate 262 to rotate, completing the torsional action. In the above-mentioned textile toughness testing device, the first gear 42 meshes with the arc-shaped toothed plate 43 to transmit torsional power. The arc-shaped toothed plate 43 moves in the moving shell 262. 5. When rotating, it drives the first gear 42 to rotate, generating a torsional torque. The support frame 44 fixes the position of the baffle 45, keeping the baffle 45 stable. The baffle 45 provides a reaction force fulcrum for the arc-shaped toothed plate 43, forcing the arc-shaped toothed plate 43 to rotate. In the above-mentioned textile toughness testing device, the first clamping plate 261 fixes one end of the fabric and is connected to the tensile gauge 34 to transmit the tensile signal. The second clamping plate 262 fixes the other end of the fabric and rotates with the rotating shaft 41, cooperating with the first clamping plate 261 to apply forces in different directions. The rotating pressure plate 263 presses the fabric tightly. The rotating action locks the end of the fabric. The fixed shell 264 accommodates the limiting groove 5 and rotates with the rotating pressure plate 263, guiding the screw 267 to insert. The rotating seat 266 allows the screw 267 to change its angle, so that the screw 267 can be smoothly screwed into the limiting groove 5. The screw 267, together with the knob 268, locks the rotating pressure plate 263. The pressing is achieved through the threaded connection. The knob 268 rotates to press the fixed shell 264. The locking force is applied by manual rotation. In the above-mentioned textile toughness testing device, the limiting groove 5 guides and positions the insertion end of the screw 267 to prevent it from loosening after locking.

[0038] Please refer to Example 2 Figures 1-11Based on Embodiment 1, the clamping assembly 26 includes a first clamping plate 261 installed on one side of the tension gauge 34, a second clamping plate 262 installed on one side of the rotating shaft 41, a rotating pressure plate 263 movably connected inside the first clamping plate 261 and the second clamping plate 262, a fixed shell 264 installed on one side of the rotating pressure plate 263, a fixed seat 265 installed on one side of the first clamping plate 261 and the second clamping plate 262, a rotating seat 266 movably connected inside the fixed seat 265, a screw 267 installed on one side of the rotating seat 266, a knob 268 threadedly connected to the surface of the screw 267, a limiting groove 5 opened inside the fixed shell 264, one side of the screw 267 passing through the limiting groove 5, the top of the moving shaft 33 being fixedly connected to the support rod 24, the arc-shaped toothed plate 43 and the baffle 45 maintaining the same horizontal position, and the detection platform 1 including a support seat 101 installed at the bottom of the fixed plate 31, and the bottom of the support frame 44 being fixedly connected to the support seat 101.

[0039] Specifically, in the aforementioned textile toughness testing equipment, the drive motor 351 outputs rotational power, which, upon startup, drives the second gear 352 to rotate. The second gear 352 transmits the motor power to the third gear 353, achieving deceleration or acceleration. The third gear 353 drives the rotating column 21 to rotate, transmitting torque to the positioning mechanism 2. In the aforementioned textile toughness testing equipment, the guide groove 461 guides the pulley 465 to move, controlling the lifting and lowering of the limiting shell 463. The cam 462, in conjunction with the limiting shell 463, locks and releases the rotating shaft 41. In the textile toughness testing device described above, the limiting shell 463 locks the cam 462 to restrict its rotation, keeping the rotating shaft 41 locked. The moving rod 464 transmits the movement of the limiting shell 463, causing the limiting shell 463 to slide up and down. The pulley 465 rolls along the guide groove 461 to control the lifting and lowering of the limiting shell 463. During the rolling process, the moving rod 464 is pushed, and the tension spring 466 provides a reset force to return the limiting shell 463 to its initial position. It automatically resets after the pulley 465 disengages from the guide groove 461.

[0040] Please refer to Example 3 Figures 1-11Based on Embodiments 1 and 2, the drive assembly 35 includes a drive motor 351 installed inside the support base 101, a second gear 352 installed at the output end of the drive motor 351, and a third gear 353 installed on the surface of the rotating column 21. One side of the second gear 352 meshes with the third gear 353. The limiting assembly 46 includes a guide groove 461 formed on the top of the fixed plate 31, a cam 462 installed on the surface of the rotating shaft 41, and a limiting shell 463 slidably connected to the surface of the cam 462. The bottom of the limiting shell 463 has a movable rod 464, a pulley 465 movably connected to the bottom of the movable rod 464, a tension spring 466 sleeved on the surface of the movable rod 464, a support plate 6 slidably connected to the surface of the movable rod 464, one side of the support plate 6 is fixedly connected to the inner wall of the movable shell 25, the bottom of the arc-shaped toothed plate 43 is fixedly connected to a slide seat 7, an arc-shaped rod 8 is slidably connected inside the slide seat 7, a connecting seat 9 is fixedly connected to the surface of the arc-shaped rod 8, one side of the connecting seat 9 is fixedly connected to the movable shell 25, and springs 10 are sleeved on both sides of the surface of the arc-shaped rod 8.

[0041] Specifically: In the above-mentioned textile toughness testing device, the support plate 6 provides a sliding guide for the moving rod 464, keeping the moving rod 464 vertical and without deviation. The slide 7 allows the arc-shaped toothed plate 43 to slide along the arc-shaped rod 8, adapting to position changes under different torsion angles. In the above-mentioned textile toughness testing device, the arc-shaped rod 8 provides an arc-shaped sliding track for the slide 7, limiting the movement path of the arc-shaped toothed plate 43. The connecting seat 9 fixes the arc-shaped rod 8 on the moving shell 25, ensuring that the relative position of the arc-shaped rod 8 and the moving shell 25 remains unchanged. In the above-mentioned textile toughness testing device, the spring 10 buffers the movement of the slide 7 and resets it, pushing the arc-shaped toothed plate 43 back to the middle position after the torsion is completed.

[0042] The working principle of this invention is as follows: The operator moves both ends of the fabric to be tested into the first clamping plate 261 and the second clamping plate 262 respectively. Then, the operator manually rotates the rotating pressure plate 263, which presses the fabric tightly. Next, the operator manually rotates the screw 267, causing the screw 267 to rotate around the rotating seat 266 as its axis. When the screw 267 rotates, it inserts into the limiting groove 5. Figure 7 As shown, the knob 268 is then manually rotated. When the knob 268 rotates, it uses the thread action with the screw 267 to press against the fixing shell 264 and press the rotating pressure plate 263 to fix both ends of the fabric.

[0043] Then, the drive motor 351 is started via an external controller. The drive motor 351, in conjunction with the second gear 352, drives the third gear 353 to rotate. The third gear 353, in conjunction with the rotating column 21, drives the fixed plate 22 to rotate clockwise. The fixed plate 22, in conjunction with the telescopic tube 23 and the support rod 24, drives the moving shell 25 to rotate. Simultaneously, the moving shell 25 rotates, causing the pulley 465 to move. When the pulley 465 moves into the guide groove 461, the tension spring 466 pulls the limiting shell 463 back to its original position. As the limiting shell 463 moves, it disengages from the surface of the cam 462, thus releasing the limiting effect on the cam 462. Figure 11 As shown, the drive motor 351 is then controlled to rotate the movable housing 25. As the movable housing 25 rotates, the arc-shaped toothed plate 43 comes into contact with the baffle 45. While the arc-shaped toothed plate 43 rotates, the position of the baffle 45 remains unchanged. At this time, the arc-shaped toothed plate 43 pushes the first gear 42 to rotate. The first gear 42, in conjunction with the rotating shaft 41, drives the second clamping plate 262 to rotate. While the second clamping plate 262 rotates, the position of the first clamping plate 261 remains unchanged, thus unidirectionally twisting the fabric. The tensile force value of the fabric is fed back through the tensile gauge 34, thereby improving the testing effect of the fabric.

[0044] After the fabric twist detection is completed, the drive motor 351 is started by the external controller. The drive motor 351, together with the second gear 352, drives the third gear 353 to rotate. The third gear 353, together with the rotating column 21, drives the fixed plate 22 to rotate counterclockwise. The fixed plate 22, together with the telescopic tube 23 and the support rod 24, drives the moving shell 25 to rotate. While the support rod 24 is rotating, it drives the moving shaft 33 to rotate. While the moving shaft 33 is rotating, it slides inside the convex groove 32. When the moving shaft 33 slides inside the convex groove 32, it pushes the support rod 24 to move. When the support rod 24 moves, it drives the moving shell 25 and the second clamping plate 262 to move, thus stretching the fabric horizontally. The tensile force value of the fabric is fed back by the tensile gauge 34, thereby improving the test effect of the fabric.

[0045] After the fabric is stretched horizontally, the drive motor 351 is controlled to drive the fixed shell 264 to rotate counterclockwise. As the fixed shell 264 rotates, it drives the arc-shaped toothed plate 43 to contact the other side of the baffle 45, which can detect the twist on the other side of the fabric and further improve the test effect of the fabric.

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
